The formulation and performance of the proposed measure are compared with other similarity measures using synthetic data. A method of piecewise approximation is also implemented
to facilitate application of the proposed measure to large samples. Example applications of the proposed similarity measure are presented using mass spectrometry imaging data and gene expression microarray data. Results from synthetic and biological data indicate that the proposed measure is capable of providing meaningful discrimination between samples, and Selleckchem SB525334 that it can be a useful tool for identifying potentially related samples in large-scale biological data sets.”
“Purpose. To measure macular choroidat thickness (CT) using spectral domain optical coherence tomography (OCT) in high myopic eyes with primary
angle-open glaucoma (POAG), and to investigate whether the choroid is thinner in these eyes compared to high myopic eyes without glaucoma. Patients and methods. We conducted a cross-sectional study of forty-eight eyes with high myopic glaucoma matched with 48 highly myopic eyes without glaucoma by age, central corneal thickness and axial length (AL). OCT scans were performed with the spectral domain OCT (Topcon 2000). The subfoveal this website CT was measured between the Bruch membrane and the internal aspect of the sclera. Results. In the subgroup without glaucoma, matched with the subgroup
with glaucoma (P=0.57), by age, central corneal thickness (P=0.33) and AL (P=0.10), the mean subfoveal CT was 96.32 ti.m + 39.56 p.M. In the subgroup with glaucoma, the mean subfoveal CT was 50.44 p.ril 16.36 vim. The comparison between the two subgroups found a statistically significant difference in subfoveal CT (P smaller than 10(-4)). Conclusions. Foveal choroidal thickness is reduced in highly myopic eyes with glaucoma. The choroidal thinning can be a useful parameter for the diagnosis and the follow-up of highly myopic patients with glaucoma. (C) 2015 Elsevier Masson SAS. All rights reserved.”
“In holoendemic Plasmodium falciparum transmission areas, severe malaria primarily occurs in children aged <48 months and manifests check details as severe malarial anemia [SMA; hemoglobin (Hb) < 6.0 g/dL]. Induction of high levels of prostaglandin-E2 (PGE2) through inducible cyclooxygenase-2 (COX-2) is an important host-defense mechanism against invading pathogens. We have previously shown that COX-2-derived PGE2 levels are reduced in children residing in hyperendemic transmission regions with cerebral malaria and in those with mixed sequelae of anemia and hyperparasitemia. Our in vitro studies further demonstrated that reduced PGE2 was due to downregulation of COX-2 gene products following phagocytosis of malarial pigment (hemozoin, PfHz).
